How do you change boot-cut jeans into flare leg jeans?

You can't do that and make them look as if they were made that way.

However, there are several tutorials where you can make a slit in the leg of the jean and sew material into the cut area so that the leg flares.

You can also simply rip the seam on the outside (slit them). That used to be quite popular.
